Build more power in the safest way possible with the Edge V3 Pulsar Programmer. It adjusts your injection pulse width, injection timing, fuel rail pressure, and airflow to add 50% more power than the original V3. These parameters are the main drivers for what creates more power for the 6.6L engine on your GM Duramax. This extra power comes in the form of up to 136HP gains in horsepower and 293TQ of torque for your wheels with some trucks reaching up to 150HP. That is a ton of extra power that you have at your disposal to travel and tow whatever you need to, wherever you need to. 5 Adjustable Levels The 2020-2023 GM 6.6L Duramax Edge V3 Pulsar Programmer features 5 "on-the-fly" adjustable levels to allow for full customization of your truck's performance based on the application. With any of these levels, you will instantly see an improvement in power and throttle response. Beyond the performance adjustments, you can calibrate the speedometer based on tire and gear changes that you have made and even adjust the speed limiter to a higher maximum. When it comes to measuring how much performance you are actually getting with this programmer, Edge engineers test each kit and usually see gains of at least 3/4 of a second in the 1/4 mile with no other additional modifications made except for the Pulsar. Fits: 2020, 2021, 2022, 2023 GM 6.6L Duramax L5P Important Note: When physically changing ring and pinion gears in the late model GM trucks, the factory cruise control will be disabled. While the Pulsar will allow you to recalibrate the speedometer for that gear change, it will not re-activate the disabled cruise control system. GM has this feature laced into the engine calibration files and would require full ECM tuning to enable cruise again. Emissions: This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA.
